Description

Orthodontic appliance {apparatus for orthodontics treatment}

The present invention relates to an orthodontic device, and more particularly, to an orthodontic device for pulling the tooth to be corrected on the anterior side to the rear side of the oral cavity.

In general, occlusion refers to a state in which teeth of the upper and lower jaws are engaged with each other when the mouth is closed. In addition, malocclusion refers to an inaccurate occlusal relationship in which the arrangement of the teeth is uneven or the upper and lower interlocking state is out of the normal position for some reason, thereby causing a functional and aesthetic problem.

Here, the cause of malocclusion is known to have a large genetic effect, but may be caused by various causes such as congenital disorders such as tooth shape or size problems, environmental influences, bad habits, incorrect posture, and dental caries.

On the other hand, when malocclusion occurs, the teeth are not neat and food residues easily remain between the teeth. In addition, it is not easy to manage cleanly with accurate brushing, so oral plaque increases, and it is easy to progress to gum diseases such as dental caries and gum inflammation. In addition, if there are teeth that deviate much from normal teeth or the jaw is abnormal, there is a high possibility that damage to the teeth, such as tooth fracture, may occur when an external shock is applied.

Thus, orthodontic treatment is performed to treat the malocclusion. Here, the orthodontic treatment uses a property that moves when the tooth receives an external force.

In detail, orthodontic treatment uses a variety of devices and methods depending on the cause or time of treatment. For example, it may be classified into a device for inhibiting or enhancing the development of the upper and lower jawbone, or a device for slowly moving the tooth to a desired position. It may also be divided into removable devices that can be installed and detached in the oral cavity and fixed devices that are detached at the end of treatment after attachment to the teeth.

On the other hand, the most widely used is a fixed treatment to attach the device called a bracket to the teeth and to move the teeth using the tension of the wire such as orthodontic wire or rubber band, it can be commonly used in various types of orthodontic treatment.

In detail, the brackets are firmly attached to the surfaces of the teeth to be corrected, respectively, and the wires are fixed to interconnect the brackets. And, by adjusting the tension applied to the wire by varying the direction and the magnitude of the force applied to the wire can be to gradually move the tooth to be orthodontic. Therefore, the orthodontic tooth is subjected to orthodontic treatment while its position and posture are changed by the tension of the wire and the tooth moves little by little.

However, according to the conventional orthodontic treatment is performed by the experience of the operator, such as a dentist, the operator himself is finely controlled by repeating the process of directly pulling or releasing the wire bound to the patient's teeth without accurate conviction. . This is controlled by the preferred dental structure through repeated trial and error, there is a problem that the procedure time is increased and the inconvenience and pain of the subject is increased.

In addition, the conventional orthodontic treatment is not objective because it depends heavily on the ability of the operator, there is a problem that it is difficult to implement a generally desirable orthodontic state because the patient has to rely entirely on the experience and ability of the operator.

Moreover, the experience and knowledge of the operator is qualitative data that is difficult to record as specific data, and varies according to the ability and experience of each operator. For this reason, the preferred orthodontic model itself, which is the final purpose of orthodontics, is also formed by the subjective viewpoint or experience of the operator performing the procedure, so that the orthodontic result is not universal and objective.

On the other hand, during orthodontic treatment, the correction of moving the teeth of the anteriorly protruding anterior teeth to the lingual, for example, the palatal side is called lingual traction. This lingual traction creates a space by extracting both premolar and corrects the desired dental condition while moving the anterior teeth protruding toward the space.

At this time, the conventional lingual traction is directly transmitted to the palatal side to the wire that provides tension to the bracket attached to each tooth. Therefore, there is a problem in that the orthodontic correction is not performed such that the wire is broken or the initial tension position is changed to cause distortion or inclination of the tooth to be corrected.

In addition, in order to prevent the separation of the wire by the traction force, there was a problem that it is difficult to change the position of the wire or replace the broken wire by substantially fixing the wire and the bracket using a high-strength adhesive or the like. In addition, it was difficult to remove the high strength adhesives and wires from the brackets, and there was a need to reattach a new bracket to the teeth.

Furthermore, when the force to be pulled backward to prevent deformation and disconnection of the wire is weakly adjusted, the discomfort of the patient is increased due to a remarkable increase in the length of the anterior tooth being pulled into the space. Moreover, there is a problem in that the teeth are inclined or the vertical position is unbalanced due to the traction force to which the anterior teeth are pulled backward is limited to the position at which the wire is coupled.

Meanwhile, in the related art, a traction device for pulling the bracket to the rear of the mouth is coupled to the bracket. The towing device is opened to surround the bracket, but the inner surface is recessed to manufacture the bracket.

However, the conventional traction device has a problem in that the process of manufacturing a recessed space for coupling and towing to the bracket is complicated and cumbersome, resulting in a decrease in productivity and economy.

As shown in Figures 1 to 3, the orthodontic appliance 300 according to the present invention is provided including a correction bracket 310 and the traction fixing part 320.

Meanwhile, Orthodontic device according to the present invention can be used in the orthodontic treatment of malocclusion protruding forward of the malocclusion, especially occurring in the teeth of the anterior side, provided to be able to move the tooth to be corrected to the rear of the mouth, that is, the lingual side do. At this time, the orthodontic treatment using the orthodontic device is formed by extracting both premolar of the target tooth portion (T in Fig. 5a) containing the orthodontic teeth to form an extraction space (5 of Fig. 5a). In addition, the orthodontic appliance 300 (400 of FIG. 5A) is installed to move the target tooth part (T of FIG. 5A) so that the extraction space (5 of FIG. 5A) is closed so that the teeth to be corrected (FIG. 5A). T1) or the rear movement of the target tooth portion (T in FIG. 5A) can be towed.

Here, the target tooth part (T in FIG. 5A) is preferably understood to be an occlusal orthodontic region including at least one or more orthodontic teeth t1 substantially requiring orthodontic treatment. That is, the target tooth part (T in FIG. 5A) may include all or part of six teeth on the anterior side where malocclusion dentition is mainly generated in the oral cavity. In addition, the fixed tooth (2 of FIG. 5a) to be described later is preferably understood to be two to three teeth on the posterior side, and the traction fixing means (440 of FIG. 5a) to be described below may be fixed.

On the other hand, the orthodontic bracket 310 is attached to the surface of the tooth to be corrected (t1), the wire is provided to provide a tension for adjusting the position and angle of the tooth to be corrected (t1). In detail, the orthodontic bracket 310 has a base portion 311 which is fixed to the surface of the orthodontic tooth t1 and has a first coupling hole 312 through which a wire for providing tension is coupled in a transverse direction.

In this case, the inner surface of the base portion 311 may be formed as a mating surface 311b to be matched to the surface profile of the tooth to be corrected (t1), it may be designed individually according to the different surface profile for each tooth.

Therefore, since the mating surface 311b is matched to a specific surface profile of the orthodontic tooth t1 and aligned in a desired position, the tension of the wire is accurately transmitted, and thus the reliability of the orthodontic treatment can be significantly improved.

The mating surface 311b has an adhesive force such that it is not separated from the tooth surface by the traction force applied to the orthodontic appliance 300 and the tension of the wire in the state of being attached to the surface of the orthodontic tooth t1. Dental adhesives may be applied. Therefore, the orthodontic bracket 310 is prevented from being separated from the orthodontic tooth t1, so that a stable orthodontic treatment can be performed.

Here, the base portion 311 may be designed so that the mating surface 311b corresponds to the lingual profile of the corrective tooth t1 so as to be attached to the lingual surface of the corrective tooth t1. In addition, the base portion 311 is preferably provided with a cross-sectional area that can wrap the lingual surface of the orthodontic tooth (t1) to a certain area.

It may be designed separately.

In addition, it is preferable that the second wire accommodating part 319 is formed in communication with the protrusion coupling part 317 so as to correspond to the wire diameter but narrower than the diameter of the second coupling hole 318. Here, the second wire accommodating part 319 is preferably communicated with the outer side of the base portion 311 from the second coupling hole 318. Of course, in some cases, the second wire accommodating part 319 may communicate with the rear of the base part 311 from the second coupling hole 318.

Accordingly, the wire for orthodontics is easily inserted into the second wire accommodating part 319 formed to correspond to the wire diameter to be caught and fixed to the second coupling hole 318, and to accommodate the second wire. Since the diameter of the portion 319 is narrower than the diameter of the second coupling hole 318, the separation is difficult, so the ease of use may be significantly increased. Therefore, the wire providing the tension for adjusting the position and angle of the orthodontic tooth (t1) is selectively detached to each wire receiving portion (313,319) formed to narrower than the diameter of each of the coupling holes (312,318) excessively Problems such as disconnection due to traction or change of the orthodontic position previously planned can be solved, thereby improving the convenience of calibration.

Accordingly, the traction force applied in the first towing direction f1 is transmitted to the traction fixing part 20 as a whole, and the towing tail part 325 is driven by the traction force while the correction target tooth t1 is stably towed. ) Can be prevented from being broken from the towing fixing unit 320.

Of course, in some cases, the towing tail portion 325 is formed to be inclined at a predetermined obtuse angle with the outer surface 324 of the towing fixing portion 320 substantially continuous with the inclined rear surface of the towing fixing portion 320. It may be extended to a specific profile. Accordingly, since the orthodontic target t1 extends to be disposed as close as possible to the profile of the gum portion leading to the palate 3 side, the orthodontic appliance 300 may be more compactly installed in the oral cavity.

4 is an exemplary view showing an orthodontic appliance according to another embodiment of the present invention, Figures 5a and 5b and 5c is an exemplary view showing an orthodontic process by the orthodontic device according to another embodiment of the present invention. . In this embodiment, since the basic configuration of the calibration bracket 410 and the traction fixing part 420 is the same as the above-described embodiment, a detailed description of the same configuration is omitted.

As shown in FIGS. 4 to 5C, the plurality of orthodontic teeth t1 exist on the anterior side, and the orthodontic bracket 410 and the towing fixing part 420 are the plurality of orthodontic teeth t1. It may be provided in plurality to correspond to. Therefore, by using the orthodontic device 400, the target tooth portion T including the plurality of orthodontic teeth t1 can be pulled backwards at the same time as a whole.

Here, the orthodontic appliance 400 may be provided as a traction assembly which is further provided with a traction joint portion 430 for integrally connecting the plurality of traction fixing part 420.

Therefore, since the traction guide bar 432 extends into the relatively wide tongue-side space on the palatal side by avoiding the oral molar and the fixing bracket 441 fixed to the molar side, the installation convenience can be remarkably improved.

In addition, the rear end portion of the traction guide bar 432 is preferably formed to be round. Through this, even when the rear end of the traction guide bar 432 is moved adjacent to the tongue muscle side by the traction force, it is possible to prevent the pain and foreign body is generated by contacting or pressing the palatal tissue. In addition, the traction guide bar 432 may be connected to the traction fixing means 440 so that the rear end side is moved to the rear side in the oral cavity, rather than the front end side is slid to the front side in the oral cavity. Therefore, the front end portion of the traction guide bar 432 is in contact with the lingual surface of the orthodontic tooth (t1) in the process of moving the target tooth portion T to the rear in the oral cavity to prevent the rear movement is limited or interfered. can do.

In addition, the traction guide bar 432 may be extended in one to the rear from the intersection point corresponding to the palatal level line by the pair of extension link portion 432a is inclined, but the teeth to be corrected (t1) at the same time stable It is preferable that the pair is provided symmetrically so as to be moved rearward.

In addition, the fixing part 431 is connected to the rear end side of the towing fixing portion 420 adjacent to both ends, but the center is formed to be rounded to the rear end side of the towing guide bar 432, the neighboring correction Can be spaced from between the target teeth. Therefore, the area between the interdental of the orthodontic target tooth can be minimized, and the oral hygiene work using dental floss and the like during orthodontic treatment is easy. Furthermore, since the fixing part 431 is formed to be rounded rearward, both ends thereof may extend in a direction close to the first towing direction f1, so that the traction force to the rear is more stably transmitted to each towing fixing part 420. May be

In this case, the fixing part 431 may be formed integrally with the traction fixing part 420, as shown in the drawing, and in some cases, the fixing part, the extension link part, the traction guide bar and the first extension hook The unit may be integrally formed and a plurality of the towing fixing portions may be provided separately. Therefore, the traction fixing part 420 may be slide coupled to the orthodontic bracket 410 in a state of being fixed to each connection point of the fixing part.

Moreover, the coupling direction of the fixing portion and the towing fixing portion may also be formed corresponding to the first towing direction f1. Further, the stopper means slide-coupled from the front of the towing fixing portion and coupled to the rear side of the fixing portion is provided with a stopper means that is mutually restrained on the rear side, so that the mutual fixing force due to the pulling force in the first towing direction f1 is more firmly established. It may be formed.

On the other hand, the traction guide bar 432 is connected through, the traction fixed to the fixed area formed on both sides of the rear of the target teeth (T) in order to provide a traction in response to the first towing direction (f1) Preferably, the means 440 is further included.

In this case, as shown in the drawing, the fixing region may be formed with both side molar parts, and in some cases, the fixing bracket 441 may be fixed to the palatal side through fixing screws or the like.

In addition, the reinforcing bracket 446 may be further provided in the front and rear directions of the fixing bracket 441 to reinforce the fixing force of the fixing bracket 441. Therefore, it is possible to prevent the traction fixing means 440 from being pulled backward to the front side in the oral cavity by the tensile force of the tension connecting portion 444.

In addition, the guide parts 443 formed with the through-hole 443a formed at both sides of the traction connecting bar 442 so that the traction guide bar 432 is inserted therethrough so as to slide in correspondence with the first towing direction f1.

In addition, the towing connecting bar 442 may be provided with a second tension hook part 445 to which the other end of the tension connecting part 444 is selectively fastened. Therefore, when the tension connecting portion 444 is fastened to the first tension hook portion 433 and the second tension hook portion 445, the traction guide bar 432 is oral by the tension of the tension connecting portion 444. As the slide moves toward the inner lingual side, the target tooth part T may be totally pulled backward simultaneously.

Here, the tension connecting portion 444 may be provided with a rubber material that is elastically tensioned, and optionally by applying a tensile force to the traction guide bar 432 by adjusting the length interval is fastened to each tension hook portion (433, 445). The paper may be provided by a wire or a chain. At this time, the tensile connection portion 444 is made of a material that can be stably towed to the target tooth portion (T) by having a tensile force greater than the force to return to each of the corrected teeth (t1) to the original protruding position. It is preferred to be provided. Accordingly, as the traction guide bar 432 is moved backward while the gap between the front end side of the traction guide bar 432 and the traction connecting bar 442 is narrowed, the traction assembly may be pulled rearward in the oral cavity as a whole. .

On the other hand, each of the coupling direction (f3) of the plurality of orthodontic brackets 410 and the traction fixing portion 420 is preferably formed to correspond to the traction direction (f1).

In detail, the orthodontic bracket 410 may be individually designed on each orthodontic target image displayed on the image, based on a scanning image obtained by scanning the oral cavity of the orthodontic subject. Then, the design information of the towing fixing part is virtually arranged in the design information of the orthodontic bracket designed individually on the tooth to be corrected, and the design information of the fixing part which interconnects the design information of the towing fixing part is virtually arranged. Can be. At this time, the design information of the towing fixing unit is preferably understood as position information corresponding to the orthodontic bracket designed individually on the orthodontic target tooth. In addition, when the design information of the tow guide bar, the extension link part and the second extension hanger is virtually arranged and the design of the tow joint part is completed, the tow joint part 430 of the real may be manufactured.

Accordingly, the traction joint part 430 may precisely correspond to the positions of the plurality of orthodontic brackets 410 attached to the orthodontic teeth t1, respectively. have. Through this, the traction assembly is simultaneously moved to the rear of the oral cavity so that the tooth target portion T is pulled as a whole, so that the orthodontic treatment can proceed quickly.

In addition, even though the orthodontic bracket 410 is formed in different positions and directions corresponding to the orthodontic teeth t1, the coupling direction f3 of the towing fixing unit 420 is formed to be substantially parallel to each other. Therefore, inclination or distortion of each tooth is prevented in the rear towing process, and the reliability of the orthodontic treatment can be significantly improved.

In addition, each position of the towing fixing part 420 is manufactured in a state arranged to correspond to each position to which the orthodontic bracket 410 is attached. Therefore, since the plurality of towing fixing portions 420 are simultaneously coupled to the plurality of calibration brackets 410, the installation convenience can be significantly improved.

Meanwhile, referring to FIGS. 5A to 5C, both premolar teeth of the target tooth part T, in which the plurality of orthodontic teeth t1 protrude forward, are extracted to form the extraction space 5. The pair of fixing brackets 441 are fixed to the fixing teeth 2 on both sides of the fixing region. In this case, each inner surface of the pair of fixing brackets 441 may be designed to mate with the fixing surfaces of the fixing teeth 2. Therefore, the through direction of the guide part 443 provided in the towing connecting bar 442 connecting between the pair of fixing brackets 441 may be installed to correspond to the first towing direction f1.

At this time, the orthodontic bracket 410 is separately attached to each orthodontic target t1 of the target tooth part T. Here, each inner surface of the orthodontic bracket 410 may be formed so as to be individually mated with the lingual surface of each of the orthodontic teeth (t1).

In addition, the plurality of traction fixing parts 420 are integrally connected to the traction joint part 430 corresponding to the position where the calibration bracket 410 is installed. When the traction guide bar 432 is moved backward while being inserted into the through hole 443a of the guide part 443, the plurality of traction fixing parts 420 are provided with the plurality of calibration brackets 410. The traction force acts in the first towing direction f1 in the engaged and fixed state. In this case, when each end of the tension connecting portion 444 is connected to the first tension hook portion 433 and the second tension hook portion 445 and a tensile force is applied, the traction guide bar 432 is the through-hole In the state inserted in 443a, the vehicle is pulled back in the oral cavity corresponding to the first towing direction f1. Therefore, the plurality of orthodontic targets t1 included in the target tooth part T may be simultaneously pulled toward the tongue muscle and the position of the protruding anterior side protruding while closing the extraction space 5 may be firstly corrected.

That is, in the present invention, the traction force to be pulled to the rear side through the traction fixing part 420 is fixed to the orthodontic bracket 410 is transmitted. At this time, the round protrusion 422 formed in the traction fixing part 420 is fitted and fixed to both edges of the second coupling hole 418 formed in the orthodontic bracket 410, and the orthodontic bracket 410 And since the elastic band is locked and fixed to the closed curved line profile formed along the side of the traction fixing section 420, the traction force can be transmitted to the entire area of the orthodontic bracket 410.

Therefore, the tooth t1 to be corrected can be stably pulled in response to the first towing direction f1 as a whole without distortion or inclination. In addition, since problems such as disconnection due to traction applied to the thin wire connecting the bracket or the previously planned orthodontic position change are solved, reliability of the orthodontic treatment may be improved.

Then, the elastic band is removed in a state where the position of the target tooth part T is moved backward, and when the round protrusion 422 is separated from the second coupling hole 418, the plurality of traction fixing parts ( 420 may be separated from the plurality of orthodontic brackets 410.

Here, the wires 16 are respectively connected to the first coupling holes 412 and the second coupling holes 418 to connect the plurality of calibration brackets 410 in which the plurality of towing fixing parts 420 are separated. Can be combined. In addition, the position and the direction may be corrected in correspondence with the second towing direction that is individually set to each tooth such that the target tooth t1 corresponds to the desired continuous dental structure by the tension transmitted from the wire 16. . Here, the second towing direction is preferably understood as a direction in which the position and angle can be moved so that each of the teeth to be corrected t1 corresponds to the continuous dental structure.

Of course, in some cases, the position and the direction may first be corrected in correspondence with the second towing direction such that the target tooth part T corresponds to the desired continuous dental structure through the wire 16. In addition, the traction joint may integrally connect the plurality of traction fixing parts to be rearwardly moved in the oral cavity as a whole. In addition, the tension of the wire is transmitted to correct the teeth to be corrected in correspondence with the second towing direction (t1) and at the same time the overall position of the target teeth (T) is pulled back corresponding to the first towing direction It is also possible. In this case, the opening sides of the respective coupling holes 412 and 418 formed in the orthodontic bracket may be substantially covered by the towing fixing unit and the elastic band, thereby preventing the wire from being separated from the orthodontic bracket by the traction force. You may.

In addition, the towing fixing part 420 from which the traction joint part 430 is removed may be coupled to the orthodontic bracket 410 while the wire 16 is coupled to each of the coupling holes 412 and 418. That is, since the wire 16 itself is not directly fixed to the orthodontic bracket 410, only the towing fixing portion 420 and the elastic band is shielded by each of the coupling holes, the towing height The separation / position or positional movement of the wire 16 may be easily performed only by separating the government part 420 and the elastic band.

As such, in the present invention, the orthodontic brackets 310 and 410 and the towing fixing parts 320 and 420 are mutually coupled and fixed, and the elastic band is wrapped around the outer sides of the orthodontic brackets 310 and 410 and the towing fixing parts 320 and 420. It is towed to the posterior side of the mouth in a fixed state. Therefore, since the traction force is stably transmitted to the entire tooth, it can be quickly moved rearward without inclination or distortion of the teeth to be corrected (t1), thereby improving the reliability of the orthodontic treatment.

In addition, the wire 16 for individual calibration of each tooth may be obtained by simply separating the towing fixing portions 320 and 420 from the orthodontic brackets 310 and 410 in which the coupling holes 412 and 418 of the wire 16 are integrally formed. Can be easily tightened / detached and repositioned. Therefore, the hassle of removing the rear towing means from the oral cavity and then replacing the bracket with a wire fastening bracket can be eliminated, thereby improving the convenience of the correction. Moreover, the stability of orthodontics can be improved by preventing breakage of the wire, which is caused by applying a traction for rearward movement of the tooth to the thin wire connecting the bracket.

At this time, the direction f3 to which the traction fixing parts 320 and 420 are coupled to the orthodontic brackets 310 and 410 and the first towing direction f1 to the rear correspond to each other. Therefore, the orthodontic brackets 310 and 410 and the towing fixing parts 320 and 420 are coupled to each other, and the outer surfaces of the orthodontic brackets 310 and 410 and the towing fixing parts 320 and 420 are fixed by the elastic band. At the same time as the towing, a strong bonding force is applied, so it can be stably calibrated without being separated from each other during the calibration period.

In addition, when a plurality of teeth are provided as a single pull assembly to simultaneously back-tighten, each coupling direction f1 of the plurality of orthodontic brackets 310 and 410 and the towing fixing parts 320 and 420 is formed in parallel. Therefore, the towing assembly can be combined and towed at one time by one operation, so that the installation convenience and the calibration speed can be significantly improved. In addition, since the overall shape of the orthodontic device (300,400) substantially corresponds to the profile leading to the orthodontic teeth (t1) and palate (3) side is compactly installed in the oral cavity to minimize the discomfort and resulting discomfort of the orthodontic target Can be.
